Scheduled Tribes. Spatial Distribution

Scheduled Tribes (STs) in India constitute indigenous communities defined by geographical isolation, distinctive culture, shyness of contact with the community at large, and socioeconomic backwardness. According to the 2011 Census of India, Scheduled Tribes account for 8.6% of the country’s total population, numbering approximately 10.43 crore individuals. The rural ST population stands at 9.38 crore, while the urban ST population is 1.05 crore.

Constitutional Provisions Governing Scheduled Tribes

• Article 366(25): Defines Scheduled Tribes as such tribes or tribal communities as are deemed under Article 342 to be Scheduled Tribes for the purposes of the Constitution.
• Article 342(1): Empowers the President of India, after consultation with the Governor of a State, to specify the tribes or tribal communities deemed to be Scheduled Tribes in relation to that State or Union Territory.
• Fifth Schedule: Provides for the administration and control of Scheduled Areas and Scheduled Tribes in states other than Assam, Meghalaya, Tripura, and Mizoram.
• Sixth Schedule: Deals with the administration of tribal areas in the four northeastern states of Assam, Meghalaya, Tripura, and Mizoram through Autonomous District Councils (ADCs).

Particularly Vulnerable Tribal Groups (PVTGs)

Within the Scheduled Tribes, a more vulnerable category exists known as Particularly Vulnerable Tribal Groups (PVTGs). Created on the recommendation of the Dhebar Commission (1960–1961), this category identifies groups characterized by a pre-agricultural level of technology, stagnant or declining population, extremely low literacy, and a subsistence level of economy.

Spatial Distribution of Scheduled Tribes across India

The tribal population in India is not uniformly distributed but is concentrated in specific geo-cultural zones. These zones exhibit distinct ecological features, language families, and socioeconomic patterns.

Regional Classification of Tribal Zones

Central Tribal Zone

This zone stretches from Gujarat in the west to West Bengal in the east, encompassing Madhya Pradesh, Chhattisgarh, Jharkhand, Odisha, and parts of Maharashtra and Andhra Pradesh. It contains over 70% of the total tribal population of India. Major tribes include the Gonds, Bhils, Santals, Oraons, Hos, and Mundas. The region is characterized by hilly terrains, plateau landforms (Chota Nagpur Plateau), and significant mineral reserves.

Northeast Tribal Zone

This zone comprises the seven sister states of Assam, Meghalaya, Tripura, Mizoram, Manipur, Nagaland, and Arunachal Pradesh. Tribes here constitute a significant majority of the state populations (e.g., Mizoram and Nagaland exceed 85% ST population). Major tribes include the Nagas, Mizos, Khasis, Garos, Jaintias, Bodos, and Mishmis. They predominantly belong to the Mongoloid racial stock and speak Tibeto-Burman languages.

Southern Tribal Zone

This zone spans the states of Karnataka, Tamil Nadu, Kerala, and parts of Telangana and Andhra Pradesh. The tribal population is highly fragmented and pocket-based, living mainly in the Western and Eastern Ghats. Key tribes include the Todas, Kotas, Kurumbas, Chenchus, and Kadars. Many of these groups are small in number and qualify as PVTGs.

Northern and Northwestern Zone

This zone includes Jammu and Kashmir, Ladakh, Himachal Pradesh, Uttarakhand, and parts of Rajasthan. Tribes reside primarily in the high-altitude Himalayan valleys and arid zones. Key tribes include the Gujjars, Bakarwals, Gaddis, Kinnaurs, Tharus, and Meenas.

Island Region Zone

This distinct ecological zone includes the Andaman and Nicobar Islands and Lakshadweep. The Andaman Islands house Negrito tribes (Great Andamanese, Onge, Jarawa, Sentinelese), while the Nicobar Islands house Mongoloid tribes (Nicobarese, Shompen). Lakshadweep, though predominantly Muslim, treats its entire native population as Scheduled Tribes due to their social and geographical isolation.

Demographic Characteristics, Social Geography, and Livelihoods

The social geography of Indian tribes is heavily intertwined with their environment, which dictates their economy, settlement patterns, and demographic indicators like sex ratio and literacy.

Tribal Demography and Literacy

• Sex Ratio: The sex ratio among Scheduled Tribes is 990 females per 1,000 males (2011 Census), which is significantly higher than the national average of 943. This reflects a relatively higher status of women and fewer instances of female foeticide in tribal societies.
• Literacy Rate: The literacy rate among STs stands at 59% compared to the national literacy rate of 73%. Literacy is lowest among ST women (around 49.4%) and shows extreme regional variation, with northeastern states showing high literacy (e.g., Mizoram ST literacy exceeds 91%) and central Indian states showing lower trends.

Economic Geography and Livelihoods

• Shifting Cultivation: Known variously as Jhum in the Northeast, Podu in Andhra Pradesh and Odisha, and Bewar or Dahiya in Madhya Pradesh. It involves clearing forest patches, burning the residue, and cultivating crops for a few cycles before abandoning the land to recover.
• Forest-Based Economy: A large proportion of central and southern Indian tribes depend on the collection and sale of Minor Forest Produce (MFP) such as Tendu leaves, mahua flowers, honey, and lac. The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, legally recognizes these community forest rights.
• Pastoral Nomadism: Practiced by Himalayan tribes such as the Gaddis and Bakarwals, who engage in transhumance—the seasonal movement of livestock between summer pastures in high mountains and winter pastures in lower valleys.

Tribal Migration: Patterns, Drivers, and Consequences

Tribal migration in India has shifted significantly from historical patterns of structural stability to modern patterns of forced distress migration.

Types of Tribal Migration

• Rural-to-Rural Seasonal Migration: Driven by the agricultural cycle. Tribal laborers move from resource-poor regions (like Chota Nagpur or Western Odisha) to resource-rich agricultural belts (like the irrigated fields of Punjab, Haryana, or coastal Andhra Pradesh) during harvesting seasons.
• Rural-to-Urban Permanent/Semi-Permanent Migration: Migration toward metropolitan cities and industrial hubs for employment in the informal sector, manufacturing, construction, and domestic work.

Push and Pull Factors Driving Tribal Migration

Push Factors (Distress Drivers)

• Land Alienation: Encroachment on tribal lands by non-tribals, money lenders, and corporate bodies, reducing landholding sizes.
• Development-Induced Displacement: Large-scale infrastructure projects, mega-dams (e.g., Narmada Valley projects), mining operations in central India, and the declaration of wildlife sanctuaries have historically displaced millions of tribals from their ancestral habitats.
• Environmental Degradation: Deforestation and declining soil fertility reduce the viability of traditional forest-based and subsistence agricultural livelihoods.

Pull Factors (Attraction Drivers)

• Wage Differentials: Higher daily wages in urban construction sites, plantations (e.g., tea estates in Assam, coffee estates in Kodagu), and brick kilns compared to local wages.
• Employment Opportunities: Growth of the informal economy in urban centers offering low-skilled manual work.

Socioeconomic Consequences of Migration

• Loss of Cultural Identity: Displacement and migration alienate tribals from their clan networks, traditional languages, and animistic religious practices (e.g., Sarna faith), leading to assimilation into the urban underclass.
• Deplorable Living Conditions: Migrant tribal laborers frequently settle in urban slums, lacking access to clean drinking water, sanitation, and formal healthcare, making them vulnerable to occupational diseases.
• The “Drop-Out” Phenomenon: Seasonal migration disrupts the formal education of tribal children, who travel with their parents, leading to high school drop-out rates and perpetuating the cycle of low literacy.
• Feminization of Tribal Agriculture: As adult males migrate for seasonal work, the burden of managing subsistence agriculture, livestock, and households falls disproportionately on tribal women left behind in villages.

• Largest Tribe: The Bhil tribe is the largest tribal group in India according to the 2011 Census, making up more than 37% of the total ST population, followed closely by the Gond tribe.
• First Tribal President: Smt. Droupadi Murmu, the 15th President of India, belongs to the Santhal tribe of Odisha, marking a historic milestone for tribal representation.
• The Sentinelese: Inhabiting the North Sentinel Island of the Andamans, they are among the world’s last uncontacted peoples and maintain total isolation from external civilization.
• Matrilineal Tribal Societies: The Khasis and Garos of Meghalaya follow a matrilineal system where lineage and inheritance are traced through the mother, and the youngest daughter (Khadduh among Khasis) inherits the ancestral property.
• The Ghotul System: A traditional socio-educational institution found among the Muria and Gond tribes of Chhattisgarh, where youth live communally to learn tribal lore, ethics, songs, and social responsibilities.
